How did DCG go for ya???

Was it just me or was that goegraphical goemetry far too easy... I hope I didnt make a mistake...

user12

I only got part A of it but I thought that was dead easy!!

user12

I was abit annoyed that the triangle question was changed dramaticalll!

Rossie17

Oh yeah, I got two separate lines for that. I think it was a simply inclined plane?

****. ****. ****. Bastid. Bollox...

Yep, I'm sure I did ****e! Got two questions almost fully out, part a of geographic geometry, 2.5 short questions, and just started b2

The tersecting planes were ABC and ABD so the line of intersection was AB....jus look perpendicular to it in plan, then along it and it gave dihedral angle (was around 160 r 170 degrees)

The hyperbolic parabaloid was píss easy...the woman with the hat one....dead simple!

The interpenetration took about 15mins....didn't even need an auxiliary!

Geologica Geometry was easy....given the strike, dip took 2 or 3 mins to get, then jus measure 25mm away and draw another parallel line which gives the footwall....thickness of the stratum was just the shortest dist between headwall and footwall...

Parabola in section A was dead simple, Oblique plane in section A was straightforward....

...finished over an hour early....reckon I got a solid A anyway:D

Pretty Tricky. I wonder how much Aviva paid the SEC for that question
What did ye get for the thicnkess in geologic geometry? Roughly 40 or 50 mm?

Couldn't have gone better tbh. I think the only thing i didn't do great was getting the vertical and horizontal traces in the planes question. Depending on how good my project is, i could possibly get an A1!

I officially hate anyone who thought it was easy. No offence.

Rossie17

To get the dip what did you guys do... I just extended the strike and the points as a single line. Found the dip. Then I marked 25 back from f and found the perpendicular distance. That was too easy I hope I didnt miss something?

Thought the Dynamic mechanisms was grand but jesus the assembly! I just couldn't picture what went where....Ended up drawing components randomly :D I'll lose marks for positioning I know...

Anyone remember what angle they got for the cut plane yoke in Sec A?

I'd be very, very happy to pass

There wasn't an interpenetration, or I hope there wasn't anyway cos I was banking on it! Other than that I was very happy with the paper, Roads was easy and planes was grand aswell, did all of Section B but 2 of those q's weren't learnt by me so I'll lose some marks there. Overall it was a lot better than expected!

Rossie17

You had to find the angle? **** I must have missed that bit I just drew the object cut in plan + elevation..

There was no interpenetration was there?

45 degrees, They'll give anything between 40 and 50 degrees

the only difference was that u were given the line of intersection this year as opposed to having to find it last year. my dihedral angle was about 165-170 degrees:P awesome test overall:P:D

how big was the semicircle supposed to be.. i guessed 10mm... other than that it was really easy.. the rising road part was all embankments so it was just 10mm apart the whole way across and that was it..

Not in B anyway. Also this year was a lot easier than last year. Hopefully they mark the projects harder to make up for it.

ya i did 10 too it was right :P

Yeah grandest.. For the hyperbollic parabaloid (hat) question, did anyone else get the horizontal trace parallel to BC? If not, how did you do it? ha:pac:

Eire-Dearg

Can't believe how easy it was.

Section C was piss easy. We've been doing those hard surface geometry Qs out of the Folens books and this was ten times easier, plus our teacher just went over it this morning in due time.

Road and mining was a little weird, why did the division of lines one of the lines on the triangle?

The perspective was tricky but I think I got it completely right, aux VPs and all!

The one thing I didn't get was the last part of the planes one.

ya it was meant to be parralel to bc you have it so that it contains ad then bring it over to contain bc extend it ti touch the gound line and bring it straight up and bring B on elevation across to touch it ( thats your point on vertical trace) then just join wher ad touches the gound line to that point and there u have it

Was easy apart from the assembly was fairy horrible..

did u mean that u get where BC touches the ground line ya?

You know when you walk into a Korean restaurant and you're not entirely sure of the language. You basically pick something at random and hope for the best, you're optimistic about your choice. Next thing the waiter comes out with a brain hemorrhage on a bed of toenails. Ladies and gentlemen.... That is how the Design exam went

dazco

Can someone just tell me in Q B-2 Part D what's the true angle between traces?
I wrote at the bottom of the page that it would be 90 degrees, cause they're on the vertical and horizontal planes.....
I got the angle of inclination to the horizontal plane just in case though as well cause I didn't really understand it......

i was surprised on how easy it was ...i failed the pre like.... i feel as if a b1 is on my way now:p
